Dermatophagoides Farinae: Side Effects, Uses & Monitoring

This product is not intended for treatment of patients who do not manifest immediate hypersensitivity reactions to the allergenic extract following skin testing. Mite mixtures should not be used for diagnostic skin testing. The individual mites should be used. Mite mixtures may be used for immunotherapy to treat patients who demonstrated sensi­tivity to both D. farinae and D. pteronyssinus mites. Patients who react to both D. farinae and D. pteronyssinus have demonstrated a significant cross-reactivity. Caution should be used in esca­lating treatment with mite mixtures.21 PRICK-PUNCTURE TESTING: A positive control using Histamine Phosphate is important to identify those patients whose skin may not be reactive due to medications, metabolic or other rea­sons. A diluent control, if negative, w…
